Teachers of Color and Indigenous Teachers are underrepresented in public schools across the United States of America, with Black, Indigenous, and People of Color making up roughly 37% of the adult population and 50% of children, but just 19% of the teaching force. Yet research over decades has indicated their positive impact on student learning and social and emotional development, particularly for Students of Color and Indigenous Students. A first of its kind, the Handbook of Research on Teachers of Color and Indigenous Teachers addresses key issues and obstacles to ethnoracial diversity across the life course of teachers' careers, such as recruitment and retention, professional development, and the role of minority-serving institutions. Including chapters from leading researchers and policy makers, the Handbook is designed to be an important resource to help bridge the gap between scholars, practitioners, and policy makers. In doing so, this research will serve as a launching pad for discussion and change at this critical moment in our country's history. The volume's goal is to drive conversations around the issue of ethnoracial teacher diversity and to provide concrete practices for policy makers and practitioners to enable them to make evidence-based decisions for supporting an ethnoracially diverse educator workforce, now and in the future.
